Look both universities have one edge over another , jaypee is older and more established and companies like Amazon also visits there . Package ranging in jaypee is from 3.3 to 26 lac/annum .average package is between 3.50–4.50 lac/annum . But jaypee doesn’t have strong international tieups .
Bennet is newer but have lots of international tieups and also , student review of Bennet is also as good as jaypee . You have to wait for first batch to passout to know the placement scenario of Bennet.
My verdict , if you want to study higher degrees after b.tech in foreign or want to settle in foreign Bennet will give you better chances.
